Question: Six interface units of the type shown in fig. are connected to a CPU that uses an 10 address of eight bits .Each one of the six chip select (CS) inputs in connected to different address line. Thus the high order address line is connected to the cs input of the first interface unit the two low order address line are connected to RS1 and RS0 of all six interface units. Determine the 8bit address of each register in each interface.
